Ornithorhynchus anatinus (platypus)

No other animal on Earth looks quite like the platypus, with its mixture of reptilian and mammalian features.

The most distinctive feature is the bill, which is not hard like the bill of a duck but soft and pliable. It is well supplied with nerves and is used by the animal to locate food and to find its way around under water.

Although known to have had several fossil relatives, Ornithorhynchus anatinus is the only living species of platypus.

    Distribution and ecology

  • The platypus, Ornithorhynchus anatinus

    Platypuses can live up to 21 years in the wild and have some very interesting and unusual characteristics for mammals. Perhaps most noteworthy is that they lay eggs rather than giving birth to live young. Another rare feature is the production of venom by males.
